(Bloomberg) The push to change congressional budget rules and enact tax cuts for longer than 10 years even if they add to the deficit received more support Thursday as the top Senate tax writer endorsed it. “It would be better” if the existing 10-year budget window were extended, Senate Finance Chairman Orrin Hatch said in an interview. “The 10 years is problematic,” he said. “I would like to do that.” A leader of the conservative House Freedom Caucus said he’s open to the idea.
